Document Type and Number:
Japanese Patent JP2023103383
Kind Code:
A
Abstract:
To minimize a time during which a specific user occupies a resource of a wireless power feeding device when a mobile terminal device is wirelessly powered, and to facilitate sharing of the resource by a plurality of users.SOLUTION: In a wireless power feeding system 1 in which a master mobile terminal device A0 transmits wireless power feeding radio waves 41 and 42 to at least one or more slave mobile terminal devices A1 and A2 that operate according to control from a mobile terminal device to feed power, the master mobile terminal device includes: an inter-apparatus communication apparatus that receives a power feeding request signal from a slave mobile terminal device to the slave mobile terminal device through inter-apparatus communications 31 and 32; a power transmitting control circuit that transmits power to the slave mobile terminal device; a battery; and a control device that controls the operation of the inter-apparatus communication apparatus and the power transmitting control circuit. When the inter-apparatus communication apparatus receives the power feeding request signal, the control device detects a remaining battery level, and controls the power transmitting control circuit and the inter-apparatus communication apparatus to output electromagnetic waves for wireless power feeding according to a detection result of the remaining battery level.SELECTED DRAWING: Figure 1
